BLIS problems and heating problems

Hello Together Have 2 problems with my XC 60 1. My BLIS has gone out (Meldung BLIS maintenance required) Mine says it will be installed in March a new software and additionally the contacts in the door must be greased (??) the door cover must be removed…. 2. My heater will be unpleasantly cool during longer driving. Then I have to turn up the temp. to have it pleasant… Also here a software update should help. Does any of you have the same problems.
